EDWARD I. KENDALL, OF BOWDOINIIAM, MAINE.

BAG-HOLDER.

To all whom it may concern:

Be it known that I, EDWARD P. KENDALL, a citizen of the United States of America, and a resident of Bowdoinham, county of Sagadahoc, State of Maine, have invented certain new and useful Improvements in Bag-Holders, of which the following is a specification.

My invention relates to a bag filling device of that class wherein a bag is clamped and held beneath the discharge spout of the grain or other bin and the object of my invention is to construct a holder for the bag which may be quickly adjusted and easily and rapidly operated so that the grain or other material may be allowed to run into the bag and the bag connected and disconnected with great rapidity and without spilling any of the material.

The characteristic feature of my device as hereinafter set forth is a holder open in the center to permit passage of the material from the filling spout and adapted to fit more or less loosely in the mouth of the bag with a clamping device for holding the bag against the outside surface of the holder which seizes the bag so as to leave one section of its mouth free to be retained by the hand.

I illustrate my invention by means of the accompanying drawing in which- Figure 1 is a plan of a device constructed according to my invention, Fig. 2 is a side elevation, and Fig. 3 is a front elevation.

In the drawing, 9 represents the spout for the discharge of the grain or other material to be filled into the bags and g is the slide. The bag holder is located immediately be neath the spout and it is so constructed as to allow the material from the spout to pass through it into the mouth of the bag while allowing the bag to be clamped to its outer surface. As here shown, it consists of an annular holder adapted to fit into the mouth of the bag with a clamping device which will seize the mouth of the bag but will leave a portion free to be held by one hand. As here shown, this annular holder is in the form of a hollow frustum of a cone indicated at d, the large end of the cone being downward. The holder is held in a position immediately below the spout by a pair of arms cl secured to an upright Z) adjustably secured to a standard 5.

The holder 03 is preferably somewhat. smaller in diameter than the mouth of the Specification of Letters Patent.

Application filed May 29, 1909.

Serial No. 499,119.

I bag so that when the bag is passed around it there will be slack enough to be gathered in one hand to draw the bag tightly around its outer surface.

Means are provided for clamping the bag to the holder while it is being held thereon by one hand and for this purpose I make use, as here shown, of an incomplete ring c which partially surrounds the holder below the arms d and when this ring is lowered or raised, it will clamp the bag to the holder or release it by reason of the conical form of the surface. Means controlled by the foot are provided for raising and lowering the clamping ring.

As here shown, a horizontal arm 0 connects the ring with a vertical guide 6 adapted to slide in a bearing 6 secured to the standard I) and connected at its lower end with the rear end of a foot lever f pivoted to a bearing 7 on the base plate a to which the standard 6 is secured. The guide 6 is preferably provided with suitable means for adjusting its length whereby the height of the foot lever above the base may be regulated. As shown the guide is made in two portions an upper portionand a lower portion 6*, the former telescoping in the latter and the two parts being adjustably secured together by the nut 6 The vertical adjustability of the upright 1) enables it to be raised or lowered to accommodate different lengths of bags.

In weighing bulky material, it is necessary to settle and compact it in the bag after the required amount has been drawn down below the slide and weighed and to accomplish this, it is desirable to have aconsiderable storage space above the mouth of the bag in which the material can accumulate before settling and without interfering with the correct weight. To provide such a space, I attach on the top of the holder d a hopper or funnel h preferably made removable and extending high enough to inclose the lower end of the spout as shown in Fig. 2. In practice the funnel it sets loosely in the upper end of the holder d and incloses the lower end of the spout.

In the operation of my device, the foot is placed on the foot lever and the ring lifted above its normal position. The upper end or mouth of the bag is then thrown over the holder by a movement of the two hands, one hand gathering a portion of the bag opposite the open space in the ring and drawing the remainder of the bag tightly about the holder. The foot is now taken from the lever allowing the ring to fall of its own weight, clamping the bag solidly on the form and entirely clearing the hand which grasps the slack of the bag. During this time the hand which does not grasp the bag after making the quick movement in throwing the bag over the form, reaches up and draws out the slide retaining its hold on the same until the bag is filled, when the slide is closed. The clamp is now released by the foot lever and the bag seized by both hands and set one side. The operation which I have described is carried out with great rapidity because the bag does not have to be fitted carefully over a form about its same size such as is common in other bag holders but being considerably larger than the holder it can be drawn around it quickly. The hand which grasps the bag to take up the slack does not leave I its hold on the bag until the clamp takes hold and is not interfered with by the clamping device. One of the advantages of my device is that none of the grain or other material is spilled since one hand is almost constantly on the shut off and the other hand has hold of the bag until it is finally clamped.

It will be seen that by the use of this device a larger quantity of bulky material may be filled into a bag than when there is a limited storage space or no storage space above the mouth of the bag and the danger of spilling is entirely eliminated. Without this device there is a constant spilling of small quantities which in the aggregate represents a very great waste.

It will be seen that with my device, the holder may be smaller than the mouth of the bag and bags of any size may be used onasingle holder and held thereon smoothly and without wrinkles since all the slack is gathered in the hand.

In order to do the work required, it is not necessary to have the hollow holder a complete ring or a complete cone as it may be made sectional so long as it has sufficient supporting surfaces to hold the bag open and an open space on the inside to allow the material to pass through to the mouth of the bag.

I claim 1. In a bag filling device, the combination of a fixed hollow conical holder, a supporting arm secured to the upper part, an incomplete clamping ring beneath said arm partially surrounding said holder, a horizontal supporting arm for said clamping ring, a vertically movable guide rod to which said arm is secured and a foot lever for vertically moving said guide rod.

2. A bag holder comprising a stationary annular holder, a support for said holder, a perpendicularly movable clamping means complemental to said holder and slidable thereon, and mechanism for lifting said means to an inoperative position.

3. A bag holder comprising a stationary annular holder, a support for said holder, a concentrically formed and perpendicularly movable gravity clamping ring complemental to said holder and slidable thereon and having an interrupted portion, and mechanism for lifting said ring to an inop erative position.

In witness whereof I have hereunto set my hand this 20th day of May, 1909.
